Point guard Jahii Carson, Arizona State’s top recruit, has been ruled ineligible to compete as a freshman for the Sun Devils.

Carson will be permitted to practice but not to compete in the 2011-12 season. He will be considered a sophomore upon joining the team, according to The Arizona Republic, but could regain a year of eligibility if he makes sufficient progress toward a degree.

Carson was ranked the No. 33-overall prospect in the nation by Scout.com as a senior at Mesa High in Arizona. He made the squad for the United States Under-19 national team and played in eight games at the FIBA World Championships, averaging 2.1 points.

The Republic reported that Carson’s initial presentation of test scores and grade average did not meet NCAA requirements, and he attempted to re-take the ACT but did not score high enough to qualify for initial eligibility.
